DEVICE FOR OPERATING A SET OF LEVERS.

SPECIFICATION forming part of Letters Patent No. 386,776. dated July 24,1888.

Application filed June 24, 1884. Renewed April 20,-1887. Serial No.235,537. (No model.)

To all whom it may concern:

Be it known that I, Hnavnr D. GANSE, of Chicago, Cook county, Illinois,have made a new and useful Improvement in Devices for Operating a Set ofLevers, of which the following is a full, clear, and exact description,reference being had to the annexed drawings, making part of thisspecification, in which Figure 1 is aplan of theimprovement; Fig. 2,avertical longitudinal section thereof; Fig. 3, an end elevation of oneof the tumbler-supports; Fig. 4., a side elevation of one of thetumblersupports; Fig. 5, a vertical cross-scction on the line 5 5 ofFig. 6, showing three of the keys and parts immediately therewithconnected; Fig. 6, a side elevation oft-heparts shown in Fig. 5; Fig. 7,a view similar to that of Fig. 5, but showing two of the keys depressed;Fig. 8, a side elevation of the parts shown in Fig. 7, and Fig. 9another side elevation, but showing all three keys depressed and thetumbler upheld.

The sameletters of reference denote the same parts.

The present invention is the peculiar mode hereinafter described andclaimed of moving any one, as desired, of a set of levers by means ofone or more of another set of levers, the operating-levers beingless innu mbcr than those operated upon.

A A A A A A represent the set of operating-levers. Six of these leversare shown; but saving as they are less in number than thelevers moved Ido not wish to be confined to any particular number. Each of theselevers A, &c. can besi milarly and independently vibrated upon afulcrum, a, the pressure of the operators finger causing the forwardend, a, of the lever to be depressed, and a spring, a or otherequivalent means operating to restore the lever to its original positionwhen the pressure is removed.

13 B 820., representaset of tu mblers. These tumblers in numbercorrespond to the set of levers operated upon, and, if desired, they maybe considered the set of levers operated upon, or they may be consideredan intermediate set of levers whose movements, respectively, can becommunicated to the set of levers it is desired to operate upon. Thesetumblers can be similarly and independently vibrated upon a fulcrum, b.

C C C C C C represent a series of what may be termed tumbler-supports.They correspond in number with. the keys A A", &c., and they,respectively, belong to thekeys A A, &c.-that is, to each key belongs acorresponding tumblcr-support, and when a key is vibrated upon itsfulcrum the tumblersup port belonging to that key is moved, and, asfollows, the tumbler supports, as shown in Figs. 1, 2, are arrangedtransversely in the device above the keys A A, &e., and beneath thetumblers B 13 due.

The tumbler-supports at their upper edge, 0, are straight. They areadapted to tilt forward and backward in the direction of thelongitudinal axis of the device, and to this end they are,at c c,journaled in suitable bearings at the sides, respectively, of thekeyboard. The tumbler supports are tilted in one direc tion (forward, asshown in the drawings) by means of the keys, and are withdrawn into anupright position by means of the springs D D", &c.

The movements of the keys are communicated to the tumbler-supports,preferably as follows: Each key is provided with an arm, E, having aninclined portion, 0, which is adapted to bear against thetumbler-support, and substantially as shown in the various views of thedrawings. On depressing a key the arm belonging to that key is drawndownward with the key and the inclined portion 6 of the arm is forcedagainst the tumbler-support, which in consequence is tilted on itsbearings toward the forward end of the key-board. The two positions ofthe arms with reference to the tumbler-supports are shown-for instance,in Figs. 6 and 7, respectively. On releasing the key the spring I), &c.,belonging to that tumbler-support operates to restore the tumblersupportto its upright position. The springs D, 850., are connected with thetumbler-supports, respectively, by attaching the forward end of thespring to some part, say, the projection c of the tumbler-support.

The present improvement is a substitute for a portion of theconstruction shown in a ponding application of mine for a device foroperating a set of levers. In the construction referred to a series ofslides with notches irregularly distributed upon them is employed incombination with a series of tumbler-rods.

The tumbler-rods have straight continuous edges, and any tumbler-rod isadapted to drop into the slides whenever the slides are so moved endwiseas to present a continuous notch across the entire series of slidesbeneath that tumbler-rod. Now, in place of using such notched slides andtumbler rods having a smooth continuous edge and causing the slides tobe moved endwise to effect a dropping of a tumbler-rod, the presenttumbler-supports have a continuous edge, and that edge of the tumblerswhich bears upon the tumbler-supports has a series of notches, and themovement of a tumbler-rod is effected by so tilting the tumbler-supportsas to bring them, respectively, beneath the several notchesin thattumbler-rod. The distribution of the notches 1) upon the edges of theseveral tumblers is such that no two tumblers shall in that regard bealike, while every several tumbler shall admit of the entrance into allof the notches upon that one tumbler of all the tumbler-sup ports, when,by the proper combination of keys, those tumbler-supports are broughtinto their proper respective distances from each other. This isillustrated with the three tumbler-supports O (3 0 Figs. 6, 8, 9. InFig. 6 the tumbler-support G is beneath the notch bin the tumbler B, butthe tumbler-supports O G are not beneath any notches in that tumbler.The tumbler therefore remains upheld; but by operating thetumbler-supports C C so as to bring them beneath the notches b b,respectively, the tumbler drops, as shown in Figs. 7, 8. In case allthree, 0 G 0 of the tumbler-supports are moved the tumbler still remainsupheld, as in Fig. 9, for although the tumbler-supports O O are movedinto position for the tumbler to drop, the tumbler-support 0 is movedout of line with its notch b in the tumbler, and the tumbler thereforeremains upheld by the tumbler-support O-that is, each tumbler has asmany notches I) as there are tumbler-supportsand the several notches inthe various tumblers throughout the series of tumblers are so relativelydistributed that but one tumbler at a time is allowed to drop, andwhenever the tumblersupports are so relatively adjusted as to admit ofthe falling of any tumbler that combination of the keys which isemployed in producing such relative adjustment of 'the tunibler-supportsoperates to prevent any other tumbler from falling. The distribution ofnotches upon the tumblers is so made that the same combinations of keysare available as are described in my several applications for LettersPatent filed, respectively, July 17, 1882; July 18, 1883; August 6,1883; December 10, 1883. Since these combinations are there set forth nofurther reference to them is here made, it being understood that whenthe combination requires the movement of a key the notch correspondingto that key stands in the notch corresponding to that key standsdirectly over the tumbler support. (See Figs. 2 and 6.)

It will be observed that the tumbler audits support areintei-acting-tl1at is, the tumbler drops by reason of its gravity and byreason of the relative shape of the notch in the tumbier and thatportion of the tumbler-support which enters the notch, substantiallyasshown in Fig. 6-for instance, the returning of the tumbler-supportinto its upright position operates to lift the tumbler so as todisengage the tumbler-support from the notch. I do not in all cases wishto be confined to this mode of disengaging and lifting the tumblers.They may be lifted by auxiliary means, (not here shown,) which auxiliarymeans may in turn be operated by the keys in their movement; nor do Iwish to be limited to a tumbler which in its movement is adapted to turnupon a pivot, as here shown; nor do I wish to be limited to a tiltingtumbler-support; for in place of such a tumbler and such atumblersupport the tumbler may be adapted to be raised and lowered in adirectly vertical direction, and the tumbler support may be adapted tobe moved bodily sidewise, so as to come into and out of line with itsnotch in the tumblers above. I prefer, however, the construction shown.

I am aware that heretofore in a mechanism for perforating paper fortelegraphic purposes there has been described a series ofpunch-selecting bars which are pivoted at one end and whose edges arenotched, the notches being differently distributed upon the several barsand with a view to selection among the bars by means of edges, which atthe will of the operator will or will not enter the notches. Themechanism referred to, however, differs essentially from the presentimprovement, in this: it makes simultaneous selection of several bars,whereas in the present instance but one tumbler is selected at one time,and by no manipulation can more than one tumbler be selected at onetime. This difference in turn hinges on another difference equallyradical. The mechanism referred to selects not by inserting theselecting-edge into the notch of the punch-selecting bar but by bringingup that edge against the solid metal of the bar. When the edge meetsnothing but a notch, it makes no selection, for selection is made bylifting the bar, and when the lifting-lever meets a notch it simplyenters it and does nothing. It further follows that when any singlelever meeting a solid part of the bar lifts that bar the other levers,if they be lifted, do not even enter the notches of that bar, for theone lifting lever carries up bar, notches, and all. In the presentconstruction,on the other hand, the selection is effected by theentrance of the edges into the notches, and therefore by the entrance ofall the edges into their respective notches. In the one mechanism thetouching of asingle selecting-edge to the unnotehed part of the bareffects the selection of that therein, as described, so that there is ineach IO bar. In the other (the present) mechanism tumbler a notchcorresponding to every tumsuch a contact of the selecting-edge with anbler-support, andsaid tumbler-supports being unnotohed part of thetumbler prevents semovable to enable them to enter said notches,
